It 45 showing still a further modified form of strip. will be also noted that the Strip. member 7 Figure 5 is a View similar to the preceding minates in a substantially straight end member views, illustrating a still further modification of the strip. It will also be seen that the sash 5 is grooved Figures 6 and 7 are Views similar to the to receiveasecond Weatherstrip member 11,which ceding views showing a modified form of strip is secured to the sash by nails or screws, or other suitable for somewhat different type of 'instalfastening means indieatedet ThiS groove, lation of course, extends the height of the window sash Figures 8 to 13 inclusive are also similar views and on each side, and its depth is such as to propshowing still further modified forms of weather erly accommodate the parts of the Weatherstrip strip. assembly. It will be seen in this form of the strip that the member 11 is bent into a substantially 8 form, the legs'of which are substantially parallel, forming a pair of channels into the outer one of which the end 10 of the strip member 7 is received. It will also be seen that the window frame 1 is grooved to frictionally receive between itself and theparting strip 4 a third Weatherstrip member 13Which is shaped in the form of an inverted L, one side of which projects into the inside channel of the member 11, suitably secured to prevent slipping, and if the width of the space between the window frame 1 and the sash 5 varies through swelling and contraction of the frame or sash,

or both, there will result a corresponding effect upon the Weatherstrip member 7 which will tend to force this member to close or open the clearance space between the sash and frame, such movement will be transmitted from the strip member 11 to the end 10 which will thus assureaself-adjustment of the parts of the strip to main tain at all times a complete closure-of the cracks of the window.

In the form illustrated in Figure 2, it will be observed-that thestrip member 7a, corresponding to the member 7. in Figure 1, has its=upper end 10a bent in the form of aninverted U to provide a channel forthe reception of the outer leg of the Weatherstrip member 11a which is here bent in the form of an inverted M, forming inner andouter channels into which project the legs of theturned end 10d of the stripmember 7a and the. side of the third stripsmember 13a which is shapedin the form of an inverted L as in the construction of Figure 1. The stop 2 and the window frame 1 are grooved to frictionally. receive and tightly hold the stripmember 7a and 13a as previously described, the strip member 130 being tightly held between the window frame 1 and thepairting strip 4' aspreviously described.

In Figure 3 the sash 6 is provided-with a groove for the reception of the end 101) of the strip member 7b,;corresp0nding to the strip member '7 and: 7a. of the precedingly described. modifications. In this form of ,the device the strip member 11b',.which is nailed or. otherwise suitably seside of the inverted L-shaped strip member 13b,

the other side of which is frictionally held between the parting strip 4 and the window frame 1. Figure 4 shows a somewhat simpler form of installation wherein the strip member '70 terminates in the straight end portion 100 which is received when installed between the sash G and one side of the L-shaped member llcwhich is secured-tothe sashfi. It willbe observed that in this instance the memberllc is simply bent at right angles and does not have its depending side bent back upon itself, but terminates in a straight member. As before, the member 110 is securedby'nails orother fastening means'to the sash 6.. Asrbefore, a reverse and-inverted L- shaped: member 130 is secured between the parting strip 4 and the window frame 1. This membet-serves as a bearing to protect the member 110 from. catching into the frame 1. V

In Figure 5' the member 11d, nailed or other-- wise secured to the sash 6, is bent at right angles downwardly and then folded back upon itself and then bentover to form a U-shaped channel, and in this modification. the Weatherstrip element 7 13dsecured between the parting strip 4 and" the In Figures 6 and 7 there are shown two modi fications of a generally different type of installa- "tion from that described in Figures 1 to 5 inclusive. It willbe noted from the drawings that in Figures 6 and 7 the installation of the strip elements is in general at right angles to the form of installation shown in Figures 1 to 5 inclusive, although the elements making up the strip installation are generally thesame as in the preceding illustrations.

In Figure 6, as before, the strip element 76 is secured in the groove cut in the stop 3, and is then bent inwardly as shown at 16 and then outwardly as at 17', forming a U-shaped channel.

The Weatherstrip member He is bent inwardly as indicated at 18 forming a U-shaped channel in which the portion 17 of the strip element '72 is received and is then bent outwardly at 19 forming a- U-shaped channel which is for the reception of the end portion 20 of the strip element 136, which is'now bent into a Z-shape as will be apparent from Figure 6 but which is still frictionally re tained between the parting strip 4 and the window frame 1. The Weatherstrip member 11a is stillfastened to the sash 6 by a nail or screw, or other fastening device, and is relatively deeply grooved for the reception ofthe bent portion of the three strip elements as will be apparent from the drawings. As will be noted, the groove and the sash member in this modification lies normal to'the groove shown in Figures 1 to 5 inclusive, and properly accommodates the parts "of the Weatherstrip assembly; J It' is also to be observed that the member 7e by virtue of; its U-shaped portion 16, which is stationary with respect to the window frame, and which encloses the sealing surfaces 20 and 19 of the strips 13c andl'le respectively, acts as a housing for-protecting the aforesaid sealing surfaces from direct exposure to the elements, as well as extraneous material such as grit, dust, etc. An additional advantage afforded by the housing may be pointed out by way of detailing a disadvantage that occurs where certain types of twopart strips are employed; In the two-part assemblies referred to, the sealing surface of the frame member is exposed, upon the raising of the sash", and as a result the frame strip is apt to receive a coat of paint when the painter touches up the sills and sash, unless particular care is' y particularly on new houses, are subject to a great loss-in efficiency from this source.

Now by way of my third strip member which embodies protective housing or sheath that on its outer surface affords no bearing or sliding contact with another part, and is stationary with-respect to the frame, I am enabled to afford protectionto the sealing surfaces of the other two strip members, either with each other or with the third strip against paint, dust, dirt, etc., and as far as coating is concerned, the painter does not have to exercise the care required for other types of strip assemblies. The outer part or housing may be given a coat of paint to beautify, as an ancillary advantage, the window and frame, by lending the same a similarity of color, and further, the paint affords a protection not ordinarily offered to such constructions.

It is also to be observed that in assemblies such as that shown in Figure 6, the member 13e may be omitted from the combination of parts without in any way destroying the seal between the sash and the frame and that the member 16 also presents an outer housing which protects the sealing surfaces of the parts 19 and 17. Under these conditions a two-part strip may be availed of, retaining the advantages of the protective housing.

In Figure 7 there is again the strip element 7f held in the groove in the window stop 3, and in this modification the strip element 11 is secured to the sash 6 between the sash and the frame 1. This strip 11f is extended up into the recess provided in the sash 6 being bent inwardly and then outwardly to form a U-shaped channel 21 in which channel is received the inwardly projecting end 10! of the strip member ii. In this form the strip member 13] is frictionally secured between the parting strip 4 of the window frame 1 as in the previous cases, but extends inwardly and is then bent downwardly and outwardly as indicated at 22 to form a U-shaped channel enclosing a bent portion of the other two window strip elements.

Figures 8 to 13 inclusive show a type of installation generally similar to that shown in Figures 1 to 5 inclusive.

In Figure 8 the strip 79 is again held in the groove in the stop 3 and terminates in the end portion 10g which is bent flatly upon itself. The weather strip element 11g is secured to the sash intermediate the sash 6 and parting strip 4 and is bent downwardly to form a depending leg 23, and then upwardly forming the upstanding leg 24, and then downwardly again forming the depending leg 25. Between the legs 23 and 24 there is thereby formed a U-shaped channel which receives the depending side 26 of the Weatherstrip member 139 which is again frictionally held between the parting strip 4 and the window frame member 1. The end 10g is interlocked with the member 11g in the channel between the legs 24 and 25.

In Figure 9 the Weatherstrip element 7h is secured along the runway in the window stop member 3 and has its end 10h bent flatly back upon itself and upwardly as shown at 26 forming a U-shaped channel for the reception of a second U-shaped channel formed by bending the weatherst'rip member 1172 first downwardly, as at 2'7, and then upwardly as at 28, there being received within this channel formed between the sides 27 28 the depending leg 29 formed by bending the strip 1371. at right angles downwardly. In this form of Weatherstrip, the member 26 acts as a protective housing or sheath and is possessed of the attributes set out therefor as in Figure 6.

In Figure 10, the Weatherstrip member 71' has its end portion 10i bent flatly down upon itself and the Weatherstrip lli is bent downwardly as shown at 30, then upwardly as at 31, and

downwardly again at 32. The third Weatherstrip element 131' is bent downwardly vasshown at 33, then flatly back against itself as at 34, and then downwardly to form the leg 35. It will be seen that the channel defined between the legs 30 and 31 encloses the portions 33 and 34 of the weatherstrip member 132' and the inverted channel formed between the legs 31 and 32 encloses the end 10i of the Weatherstrip 72', the side 35 of the weatherstrip element 131' being positioned between the side 32 of the Weatherstrip element 112' and the window frame 1.

In Figure 11 the Weatherstrip 77' is as before secured in the groove in the window stop 3, and has its end 107' folded fiatly downwardly upon itself and then upwardly to form the side 36 which bears against the window frame 1. The weatherstrip element 117' is again secured to the sash 6 and is bent downwardly to form the side 37, and then upwardly to form the side 38, and then downwardly to form the side 39. It will therefore be seen that there is a U-shaped channel formed between the sides 37 and 38 and an inverted U-shaped channel between the sides 38 and 39. As before, between the parting strip 4 and the window frame there is positioned a Weatherstrip element 137' which is bent downwardly at 40 to form a leg projecting to the U-shaped channel between the sides 37 and 38 of the Weatherstrip element 117', the side or leg 39 of the weatherstrip element 137' being positioned in the channel formed between the ends 109' and the side 36 of the Weatherstrip element 751', thus the bent-over end 107' being positioned in theinverted channel between the sides 38 and 39.

In Figure 12 the strip 716 is as before held-in the window strip 3 and has its end 10k engaging the window frame and is bent fiatly downwardly against itself and then upwardly to form the side 41, thus defining a U-shaped channel between this side 41 andthe bent-over end portion 10k. As before, the Weatherstrip member 11k is secured to the sash 6 and is bent down in engagement with the sash 6 forming the side 42 and is then bent upwardly forming the side 43, and then downwardly forming the side 44; The Weatherstrip member 13k secured between the parting strip 4 and the window frame 1 is bent downwardly as shown at 45, this bent portion 45 projecting into the channel defined between the sides 42 and 43 of the weatherstripelement 11k, the upstanding member41 of the weatherstrip member We being positioned within the inverted channel between the sides 43 and 44, the side 44 being in turn positioned within the channel formed between the members 41 and 10k of the Weatherstrip element 710.

In Figure 13 the strip element 7m is as before engaged in the groove in the stop 3, and in this instance the end portion 10m is bent so as to be spaced away from the window frame 1 and is then bent downwardly upon itself and then upwardly to form the side 46, there being a relatively widechannel formed between the side 46 and the side 10m. As before, secured to the sides 6 of the window sash is the element 11m which is bent downwardly to form the side 47 and then upwardly to form the side 48, thus forming a channel which is enclosed by the channel between the sides 46 and 10m of the weatherstrip 7m. The element nm is then continued,

is bent downwardly to form the side 49, this side,

49 being positioned between the end portion 10m of the Weatherstrip element 7m and the window frame 1. Also, as before, positioned between the parting strip 4 and: the window frame 1 there is the Weatherstrip element 13m which extends inwardly and is'bent downwardly at right'angles to form the. side 50, which is enclosed in the channel formed between the sides 47 and 48 which sides are also enclosed between the sides 46and 10m of the Weatherstrip element 7m.

Figures 14 and 15 show a type of installation somewhat similar to that illustrated in Figures 6 and? in that, as in-these aforesaidfigures, the installation is made in a plane at right angles to the installation of Figures 8 to 13 inclusive In Figure 14 the Weatherstrip element 711 is heldin the window stop 3 and is bent inwardly as shown at 1011, then upwardly and outwardly to form'the' side 51. Again'secur'ed to the sash 6 is the Weatherstrip lln which extends outwardly and is then bent inwardly to form the side 52, and then downwardly and outwardly to form the side 53-. The portion 51 of the Weatherstrip element 7n extends into the channel formed between the side lln and the side 52 thereof, there being a channel between the sides 52 and 53 of the element lln which receives the side 54 f the Weatherstrip element 1311. which now is frictionally held in a groove in the parting strip 4. The zone n of the member, in this assembly plays the part of a protective housing possessed of the virtues enumerated in the description of Figure 6. V 1

g In Figure theweatherstrip element is, as before, held in the groove in the window stop 3' and has its. end; 100 bent inwardly, then downwardly, andoutwardly to form the side 55. In

- this modification the Weatherstrip element 110 is secured to the sash 6 between the sash and the window'frame 1 and projects inwardly as shown at 56, which portion: is bent flatly back upon itself at 57 .and then upwardly and inwardly as shown at 58. Again positioned between the parting'strip 4 and the window frame 1 is the weatherstrip element 130 which projectsiinwardly and is bent downwardly as shown at, 59 and then outwardly at 60 to'form'a U-shaped channel en-' closing the remaining Weatherstrip construction. The portion 55 of theweatherstrip element '70 is disposed in the channel formed between the sides 57 and 58 of the Weatherstrip element 110, this entire :constructionbeing enclosed by the sides 13o, 59 and 60 of the aforesaid Weatherstrip member 130. As distinguished from the assemblies of Figures 6, 9 and 14, the strip 130. herein acts as a protective housing rather than the part 10a;

however, the desired end, asioutlined in the 'description of Figure 6, is efficiently accomplished.

In Figure 16 there is shown in perspective one form of the Weatherstrip member generally desigated-at '7; in the above description, its -projections 8 being adapted in each case to bear against.

the window sash, thus lessening friction on the window frame and preventing rattling of the sash. The configuration of a convenient channel in which this strip element 7 terminates is indicated at thebend 10 relatively adjacent one end of the strip 7 and the side 61.

In the above description, it will become apparent that the present invention is composedof a three-part window strip, one part of, which is secured within a window stop, a second part of which is secured to the window sash by a nail" or screw or similar fastening means, the third part being held .frictionally or otherwise within the parting strip 4, either within the parting strip itself, or betweenthis parting stripand the 'win-. dow frame, these parts being closely cooperative regime to closethe joints between the window stop and the frame toprevent entrance of air therein.

The strip itself, is obviously very easily installed requiring a minimumamount of. workon the sash. simplicity of installation may beincreased by using one type of strip for the upper sash and an.- other type of strip for the. lower sash, conditions of the window construction where the installation is being made being the determining factor in this instance, as will be obvious to anyone familiar with installing weatherstrips. The strip doesnot interfere in any way with the removal of the sash for repairing the sash cord or the sash, nor does the groove in the sash for the pulley cord interfere in any way with the efiiciency of the strip, since the continuity of the strip is not interrupted anywhere being installed in the corner and being protected by the parting strip, it is virtually impossible to damage the strip, and further there is no danger of its catching on the pulleys or the sash cord. It will also be seen that In some instances the efficiency and each of the illustrated forms provides at least five passages through which the air must travel to get behind the window with the exception of the form shown in Figure 3, which form, while generally satisfactory does notgive quite as much protection as the other forms herein illustrated and described. Its simplicity and ease of installation however render it meritorious. In the case where there are live passages for the air, there will be four complete reversals of directionthat the elements must pass through before entering the house, thus givingmaxim'um protection with a minimum amount of metal.

The three-part Weatherstrip construction herein provide'dby me may under some conditions be modified in its use by employing sub-combinations of the three-part structure; In other words, I may, under certain conditions, employ two of the three parts and obtain efiicient Weatherstrip construction though not as emcient as when I utilize the threeparts complete. Thus, in Figure 1, the strip memberfl13 may be omitted from the assemly or combination of parts andthe remaining partsv '7 and 11 in their cooperativerelation will afford a fairly effective Weatherstrip device useful under certain conditions of service. For another illustration, I refer to Figure 9, wherein it will be apparent that the Weatherstrip member 10H-26 may be omitted and. the remaining Weatherstrip members 13H-29 and 11H-2'1 will afford a two-part Weatherstrip effectively useful as such even though of less efficiency than the three-part strip. Of course, when the parts are arranged'aslast described, I do not have the advantage of the use of the housing portion that is employed inconjunction with the member 10H. Or again, as to the construction in Figure 9, I may omit the Weatherstrip member 13H- -29 and the remaining .two members have efiective sealing cooperation and will provide a very efficient twopart Weatherstrip. V The last described modification in principle may be adopted for the constructions in Figures 6, 13, and 14, and the remaining two-part strip will be-a useful construction, as obvious from the foregoing. In Figures 7 and 15 the frame'member may be omitted and the member that fits along the parting strip and interlocks over the sash member then forms the protective housing.

.Cln mounting my Weatherstrip construction of the window frame and. sash member, it is of special importance to note that I obtain an ease of mounting that is not to be found in certain prior constructions; for instance, I point to those constructions as shown in Figures 1, 2, 3, 4, 5, 8, 9, 10, 11, 12 and 13 wherein the groove member in the sash is of considerable depth and extends toward the stop 3 and lies between the parting strip 4 and said stop. It will be observed from these views that the sealing portions of the Weatherstrip construction lie in this-groove and are pointed, so to speak, toward the parting strip 4 or toward the stop 3. Now in assembling this construction, the strip member that lies between the frame and sliding sash, and is anchoredin stop 3, may be positioned first, and then the sash or frame member mounted in place,the manner in which the parts cooperate determining the next part to be mounted; however, usually the second part mounted is the member tacked to the sliding sash whereupon the third member may be mount ed in cooperation with the other two parts with its attaching portion lying in the notch provided in the parting strip groove. The parting strip may then be mounted in position to grip the attaching portion of the third member between it and the frame to anchor the whole construction.

It will be also apparent that the invention is capable of many modifications without departing from the inventive concept. It is understood that it is intended and desired to embrace within the scope of this invention such modifications and changes as may be necessary to adapt it to varying conditions and uses.
